For Loops
Hi everyone,
I have a question regarding for loops. I am writing a BASH shell script that will contain multiple loops. These loops all involve looping with a count:
for (( a=0; a <=10; a++ )); do
echo $a
done
If none of my multiple loops relate to each other throughout the script, is it a bad idea to use the same count variable for all of them for consistency (ie a)? Or should I use b for the next loop, c for the next, d, e, and so forth?
Once again, these variables (a,b,c ....) will only be used in their respective loops, and won't be used later on in the script.
Thanks,
Mike

sendme
sendme(8) sendme(8)
NAME
sendme - Send a signal from driver to user and measure time intervals
SYNTAX
sendme [-a|-a PROC] [-b USEC] [-l loops] [-p PRIO]
DESCRIPTION
The program sendme uses the backfire driver to send a signal from driver to user. It then reads the timestamp from the driver and calcu-
lates the time intervals to call the driver and to receive the signal from the driver.
OPTIONS
-a, --affinity[=PROC]
Run on procesor number PROC. If PROC is not specified, run on current processor.
-b, --breaktrace=USEC
Send break trace command when latency > USEC. This is a debugging option to control the latency tracer in the realtime preemption
patch. It is useful to track down unexpected large latencies on a system.
-l, --loops=LOOPS
Set the number of loops. The default is 0 (endless). This option is useful for automated tests with a given number of test cycles.
Sendme is stopped once the number of timer intervals has been reached.
-p, --prio=PRIO
Set the priority of the process.
FILES
backfire.ko
EXAMPLES
# modprobe backfire
# sendme -a -p99 -l1000000
Samples: 1000000
To: Min 0, Cur 0, Avg 1, Max 11
From: Min 2, Cur 3, Avg 3, Max 43
